The Oklahoma Education Association, the state's largest teachers' union that represents nearly 40,000 members and school personnel, called the passage of the bill "a truly historic moment," but one that remains "incomplete," according to its president, Alicia Priest.

Teachers and school staff will walk off their jobs on Monday and descend on the state Capitol, she said in video comments posted on Facebook.

Oklahoma City Public Schools said all classes and activities are canceled for that day because of the walkout.

"While this is major progress, this investment alone will not undo a decade of neglect," Priest said. "Lawmakers have left funding on the table that could be used immediately to help Oklahoma students."

"This package doesn't overcome shortfall caused by four-day weeks, overcrowded classrooms that deprive kids of the one-on-one attention they need. It's not enough," Priest said. "We must continue to push for more annual funding for our schools to reduce class size and restore more of the 28% of funds they cut from education over the last decade."

The OEA had also called for $10,000 pay raises for teachers over the next three years and $5,000 pay raises for full-time support professionals such as custodians, secretaries, bus drivers and food service workers.

"We asked for $10,000 over three years. This gets us part of the way there, and so we need to have the Legislature guarantee that we are still working to get to that," Priest had told CNN affiliate KFOR
.

Oklahoma has faced a teacher's shortage this year, and some districts have been forced to hire people without a background in education to fill voids in the classroom.

Arizona teachers: 'I don't want to strike, but I will.'

In Arizona, thousands of teachers and supporters wearing red swarmed the state Capitol on Wednesday, calling for higher pay and better education funding under what they called #REDforED
.

The color red was meant to convey their frustration, which they say has reached a crisis level. Teachers have been wearing red shirts every Wednesday and encouraging supporters to do the same, according to the Arizona Education Association, which has 20,000 members who are teachers, counselors, bus drivers and retired educators.

Arizona Educators United
, a coalition of educators, demands a 20% salary increase for teachers, competitive pay for all education support professionals, as well as education funding restored to 2008 levels.

"Our classrooms go without updated textbooks, basic supplies, and technology. We have among the highest class sizes and school counselor loads in the nation, making it difficult to meet the individual needs of our students," the group stated
.

Arizona ranks 43rd in the nation in teacher salaries, according to the National Education Association.

Teachers say they are overworked and underpaid. They want better pay and are encouraging each other to organize via social media. They're hoping their very public display of frustration will pressure state leaders, such as Gov. Doug Ducey.

State Sen. John Kavanagh, the Appropriations Committee chairman, told KNXV that tax increases to pay for K-12 education are off the table, as voters have opposed the idea in the past.
